Chevy Wilwood Master Cylinder Kit, Tandem, Black Electrocoated Aluminum, with Bracket & Valve, 1 1/8" Bore 1955-1957

The slotted flange mounting makes it a simple bolt on for Chevy OE mounts. The combination proportioning valve substantially simplifies wiring and brake proportioning adjustments on vehicles with custom brake systems. The combination block maintains full isolation between front and rear fluid circuits and is specifically designed to accompany the Tandem Chamber Master Cylinder. The combo valve and bracket are also black E-coated (electrocoated) for a performance look and long lasting durability. Stainless steel fluid tubes are precision bent with preinstalled stainless tube nuts for a simple bolt-on installation between the Combination Proportioning Valve and the Tandem Master Cylinder. Stainless steel button head fasteners thread into the bracket for a simple installation and years of durable, rust-free performance. Simply connect the fluid lines, bleed the system, and you're finished.
